Equipment Maintenance of Solid State High Frequency Welder

Why equipment maintenance?

After a period of use of Solid State High Frequency Welder, some electrical components will occur aging phenomenon, the electrical parameters change, there are some action-type electrical components may fail, the connection between the components may be loose, rust, which will affect The overall performance of the Solid State High Frequency Welder, or even failure. Therefore, the regular maintenance and maintenance of the equipment will ensure the long-term stable operation of the equipment play an important role, so the user after start use this Solid State High Frequency Welder must do regular maintenance.

Daily maintenance content

①Before the daily routine of the equipment to carry out the health work, including the outside of the cabinet wipe clean, check the cabinet door is sealed well. Whether the water system is normal. According to the specific situation when necessary use hair dryer inside the box for dust, the cabinet outside on the site should be clean.

Note: Before cleaning, you must cut off the power, in the case of power off to clean, to ensure personal safety. When cleaning, pay attention to water or oil into the cabinet.

②Check each component separately See below maintenance and maintenance requirements.

③after cleaning, first check whether missing items inside the cabinet, and then to close the door.

④ After the daily work should fill out the equipment log.

Maintenance and maintenance requirements

Maintenance of rectifier cabinet

① water pressure switch must be regularly checked, damage or setting value deviation should be timely correction, if the water pressure switch failure and negligence forget to open water, it will burn SCR, MOSFET, fast recovery diodes and other important water cooling components.

② electrical wiring should always be checked to ensure reliable contact. High-voltage lines and low-voltage lines should be kept at a sufficient distance, high-frequency lines should not be close to the door, rack. Especially important control lines, must not considered that the insulation can close to high current high-frequency lead, or easily lead to abnormal equipment work.

③ should always check the relay, contactor leads are loose, the contact is burned, the action is reliable.

④ should always check the reliability of the grounding system, grounding deterioration, will cause equipment abnormal, even cause personal accidents.

⑤ should regularly adjust the measurement system to ensure accurate measurement.For equipment normal operation,accurate measure has a very important significance.

DC voltmeter, DC ammeter, frequency meter directly response the equipment working conditions, therefore, their accuracy is critical to the state of the equipment should be adjusted regularly.

⑥ should always clean the rectifier cabinet components, keep the cabinet clean and sanitary. If you use a wet cloth to wipe, be sure to confirm the device dry and then boot.
